dynamic oxidation chamber Articles

Atmospheric emissions, transport, transformation and deposition of trace gases may be simulated through chambers. The dynamic flow-through chamber system has been developed in response to a need to measure emissions of nitrogen, sulphur and carbon compounds for a variety of field applications. Oxides of nitrogen (NO, NO2, NOY) emissions have been measured from ...

One of the biggest challenges facing oil companies today is how to extract more oil from the discoveries made in the last 40 years. Estimates vary, but approximately 66% of the discovered oil gets left in the ground. The International Energy Agency has estimated that if, in the next 20 years, this figure could be reduced to 50%, then this would increase the world's recoverable oil by 1.2 trillion ...

Soaring energy costs and the high cost of ‘end-of-pipe’ pollution control equipment has caused companies and regulatory agencies to re-evaluate ‘unconventional’ means of achieving VOC and HAP emissions control. The coatings industry is an excellent candidate for alternative, unconventional controls, as VOC and HAP reductions have not been as strident as has been the case in many other industries. ...

Slot Injector: How does the slot-shaped nozzle of the Slot Injector™ aeration system improve performance? The slot shaped nozzle and mixing chamber provide a larger shear surface for mass transfer than a circular jet of identical area. This unique shape results in a high percentage of gas dissolution and superior oxygen transfer rates with a 10-20% reduction in energy usage ...

The Rockland County (New York) Cocomposting Facility began operations in February, 1999, processing biosolids from the five publicly owned treatment works (POTWs) in the county. The Rockland County Solid Waste Management Authority (RCSWMA) owns the facility, but contracted with Waste Management of New York to design, build and operate (DBO) the 110 wet tons/day agitated bin composting facility ...

Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...
